A beam is constructed from two 50 x 100 mm wood planks that are attached by screws that are spaced at 30 cm in the longitudinal direction as shown. This built-up section is subjected to an internal shear force of 100 kN acting downwards as shown. Determine the shear strength of the screws necessary to maintain this built-up section in terms of the force that each screw must be able to carry.

Cables

Cables are collections of wires, alternatively referred to as a cord, connector, or plug. They are one or more wires covered in a plastic covering that allows for the transmission of power or data between devices. The earliest use of recognizable electrical cable was the early commercialized telegraph lines. These were iron-made and tedious to produce and install cabling.
